Revert "media: rcar_fdp1: Convert to platform remove callback returning void"

This reverts commit 5847021f which is
commit 0e82d371 upstream.

The remove_new abi change is not needed for Android systems, so revert
it for now.  The original bug that this change was needed is still
resolved properly.
